The authors proposed a new hysteresis model for R/C beams in order to investigate the remaining performance of the structures subjected to repeated seismic loads. The parameter settings included, (1) the degrading factor for loading stiffness based on the normalized dissipated energy, (2) the slipping hysteresis loop factor based on the maximum displacement and the normalized dissipated energy, and (3) the degrading factor for descending stiffness. This paper verified that the proposed model accurately simulated the test results with the parameters obtained by the experimental data. In addition, the tentative dynamic analysis incorporating the proposed model showed that the repeated seismic loads could increase seismic response.
